I do not have THE contract, I have TWO contracts relating to NAS. Each contains the clause that no 'employment relationship' exists with the lessee airline. Notwithstanding, no one has posted that their contract with OSM or Rishworth does not contain the same clause or similar. You seem to forget, the main reason airlines use agencies is to forego any employer/employee obligations.
The Kjos labor model is at best objectionable and at worst unethical. Most criticism of Norwegian's poor labor relations is not from the US but from the Scandinavian media. Earlier this month Norwegian settled a case out of court involving a Safety Officer sacked earlier this year. DN News reports a quote from a union representative:
"
It emerged very strong testimony in court which in my opinion very damaging to confidence in the management of the company and created the basis for settlement. A continuation of what we heard on Tuesday would have been so devastating for Norwegian short and long term that the company had no choice but to arrive at settlement"
